FEED MECHANISM.

Specification of Letters Patent.

Patented April 20, 1909.

Application filed September 13, 1901, Serial No. 75,305. Renewed January30, 1909. Serial No. 475,219.

To all whom it may concern:

a citizen of the United States, residing at Hartford, in the county ofHartford and State of Connecticut, have invented certain new and usefulImprovements in Feed Mechanism, of which the following is aspecification.

This invention relates to means for imparting an intermittent or step bystep movement to a member, such, for instance, as a typebar blank, or acomponent member of a composite typebar during the progress of makingthe bar.

The present invention is adapted for imparting movements to a blankwhich is to be subjected to appropriate operations to convert the sameinto a finished article, and it embodies a mechanism for feedingvariable distances a blank from which or on which types are to be madeto bring successive portions of the blank into proper relation with thetype-making mechanism. I

There is shown, described, and claimed in an application filed by me onAugust 22, 1901, Serial No. 72,884, a feeding mechanism foraccomplishing a similar movement of a blank or member as the presentinvention is adapted to attain. The invention disclosed in thatapplication embodies as an element an actuator for engaging withpreformed shoulders in the side face of the blank, and which whenrotated upon its aXis intermittently accomplishes a correspondingforward or feeding movement of the blank. There is also shown anddescribed in that application a modified form of actuator in which apretreatment of the surface of the blank is not necessary to enable theactuator to perform its function.

The invention set forth in the present application includes as a featurea form of actuator designed to likewise eiiect a feed movement of theblank without necessitating the previous formation of shoulders forengagement with the actuator; the actuator, constituting the feedelement of the present invention, being adapted to simultaneously formshoulders and engage with the shoulders thus formed to impart a stepbystep or feeding movement to the blank.

As in the invention disclosed in my com- I anion application, when thedirection of feed movement is uniformly in one direction,

I will usually employ, in the present construction a feed element oractuator adapted to engage directly with the blank and by its movementserving to shift the latter forward step by step. If the presentinvention is applied to a typebar mechanism in which a succession oftypes is produced through the action of successively-selected andoperated dies, this forward movement of the blank is advantageouslycontrolled at each step by the respective selected dies, and since thesedies represent the letters of the alphabet and other characters ofcomposition of different widths, a mechanism embodying the presentimprovements will usually include means for imparting variable movementsto the blank corresponding to the varying widths of the type-making diesor analogous instrumentalities successively brought into workingposition.

In the drawings accompanying this specification, Figure 1 is a sideelevation of a mechanism embodying my present improve ments, and whichis adapted to impart a step by step variable movement to a typebarblank,parts of the figure being broken away the better to show parts lyingbeyond. Fig. 2 is an end view of the mechanism looking from the right inFig. 1. Fig. 3 is a horizontal cross-sectional view on the lane of theline 33, in Fig. 2, some of the details being omitted. Fig. 4 is a planview of the actuator indicated and shown in the preceding figures, withcertain of its associated parts, and illustrates the actuator inengagement with a blank, certain portions being shown in section. Fig. 5is a side elevation of the parts shown in Fig. 4. Fig. 6 is across-sectional view on the plane of the line 66, in Fig. 4, looking inthe direction of the arrow adjacent to that line. Fig. 7 is aperspective view of the actuator removed from its position relatively toits bearings and t0 the blank with which it is desi ned to engage; andFig. 8 is a side view of a portion of a typebar-blank, showing theshouldenforming notches made in the side of the blank by the actuator.

Similar characters of reference designate corresponding parts inall-figures.

A typebar machine of simple construction is shown in the "drawingsattached to this specification for the purpose of disclosing anembodiment of the present invention, whichlatter, it may be stated,includes as one of its features a combined shoulder-forming andshoulder-engaging instrumentality or blank actuator adapted to formshoulders in the side face of the blank and to effect through thepositive engagement of the actuator with such shoulders the shifting ofthe blank. Combined with this shoulder-forming and shoulder-engaginginstrumentality are means for imparting a discontinuous or interruptedmotion to the actuator; this means preferably possessing a capacity ofoperation whereby the extent of the separate movements imparted to theblank, etc, are varied. It will e understood, however, that in soillustrating an application of the invention, I do not contemplate thelimitation thereof to embodiment in the specific form of mechanismshown, but consider the invention in its broad aspect to be coextensivewith the elemental organization above outlined; that is to say, asincluding any mechanism which embraces an actuator serving tosimultaneously make shoulder-forming notches in a blank or otherelement, and to engage therewith to shift the blank combined with meansfor imparting a discontinuous motion to the actuator.

Referring now particularly to the specific construction of mechanismshown, there is embodied therein a plurality of type dies appropriatefor producing a desired series of types on the edge of a blank, combinedwith means under the control of the several dies for shifting the blankalong step by step and bringing consecutive portions of the edge thereofsuccessively to the working point of the machine, at which point thedies selectively operate to produce the desired succession "of types andword-separating spaces.

The particular species of mechanism to which the present machine belongsis that wherein a rotatable die-carrieror plurality of the same ismounted upon a rotatable maincarrier or turret, which by its motionserves to convey the die-carriers past the working point, but normallyin inoperative relation with a blank located thereat.

In the construction shown, a suitable supporting base-plate, designatedin a general way by B, is provided, whereon the various operativemembers are mounted.

For the purpose of bringing a selected die to the working point andcausing its operation thereat by a rollingmovement over the edge of theblank, there is provided suitable mechanism, under the control of theoperator, for initiating, continuing, and ultimately arresting therotary motion of the particular diecarrier shaft upon which theparticular die-carrier upon which the particular die is mounted, as suchcarrier revolves about the axis of the turret.

Entering now upon a more Jar-ticular description of the various detaiisshown, the main-carrier or turret is designated in a general way by T,and embodies a shaft 2 :iounted in bearings provided in or supported onuprights 33 erected from the baseplate B. This shaft 2 is adapted tohave a rotary motion in its bearings, and for its actuation a pulley 2is shown attached thereto, which pulley may be driven by a belt from anysuitable source of power (not shown). In this instance, two die-carriers44 are shown attached to respective shafts 55, each mounted in bearingscarried by arms 66, respectively, a pair for each shaft. These armsextend from the main shaft 2 of the turret, and are rigid therewith,thus causing, during the rotation of the turret, the revolution of theshafts about the axis of the former shaft.

During the rotary movement of the turret, the dies, designated in ageneral way without preference by D, upon each of the diecarriers 4-4,are inoperative to impress a properly located and supported blank; butwhen the rotation of a die-carrier is initiated, at the proper point inthe path of orbital movement of the carrier, that die which iscoordinated with such point will, when conveyed to the working point ofthe machine, roll over the edge of a blank located thereat, and form inor on such blank a type as the result of the rolling action to which thematerial of the blank is subjected.

For the purpose of initiating the rotation of each die-carrier ordie-wheel 4, I have indicated in a conventional way the customarydevices employed in mechanisms of this class, embodying a series ofkeys, designated a general way by K attached to corresponding latches L,suitably mounted in a latch-frame 7 erected upon the base-plate B. 'lwoseries of keys and corresponding latches are herein shovm displacedaxially of the turret, each latch L, when released, being thrownii'iward toward the axis of the turret by a corresponding spring 8attached to the latch and to a fixed portion of the latchframe.

It will be understood that the key and latch mechanism described andillustrated are merely typical of a more perfect construction, since thepresent illustrated mechanism is intended as a conventionalrepresentation only.

It will be noted that each spring 8 is arranged obliquely with referenceto the axis of its corresponding latch, and that each latch is providedwith a notch 8 adapted to cooperate with the edge of the opening in thelatch-frame through which the latch moves. lfuthermore, each series oflatches in the present organization is shown as being made up of nineseparate members disposed at different points concentrically about theturret axis, although, of course, a greater or lessernumber may be used,depending upon the number of separate amounts ofrotative movements whichit is designed shall be impartable to the shafts 55 and their attacheddie-carriers.

In Fig. 2, the series of latches are severally represented in theirinoperative or retracted position. lfhen it is desired to set a latch,and hence effect the rotative movement of a die-wheel or carrier, andthe consequent operative movement of the selective die, thecorresponding key is, in the simple construction illustrated, urgedlaterally to disengage its notch 8 from the edge of the latch-frain e,whereupon the attached spring 8 projects the latch inward until itsmovement is arrested. by the contact of a shoulder 1 on the latch withthe latch-frame.

Adapted to cooperate with the latch when projected is a starting-arm 9,one for each shaft, and to which it is attached, the starting-arms forthe two shafts being arranged in the planes of the two series of latchesL. When the turret is rotating and the latches are withdrawn, nocooperation of a latch with its starting-arm takes place; but when alatch is set, the starting-arm located in the plane of that series oflatches of which the set latch forms a member upon coming into contacttherewith causes the angular movement of the shaft to which it isattached, initiating thus the rotation of the latter. According to thepresent construction, which, it will be understood, is illustrativemerely of one construction for accomplishing the same result thisrotation is continued as the result of the operation of the followingmechanism, it being premised that the mechanism for each shaft is thesame.

Surrounding each shaft 5 and com elled to rotate therewith, butshiftable aXia y of the shaft (as by a key and slot construction), is acorresponding sleeve 10, carry'mg a pinion. 11 with which there is alsofixedly related a cam-finger or cam-arm 12, here shown to be of aresilient nature. During the normal rotation of the turret,-that is,with the dies inoperative to impress a blank located at the workingpoint of the niachine,-the camarm 12 occupies a position in which it isfree from engagement with a corresponding cam 13. fhenever the shaft isstarted rotating, however, as a result of the cooperation of itsstarting arm with a projected latch, the cam arm is shifted into aposition in which it 00- operates with such cam 13. lhe inclination. ofthe surface of this cam is such that during the further cooperation ofthe starting-arm and the projected latch, it operates through thecontact of the cam-arm therewith to shift the sleeve 10 longitudinallyof the shaft 5 and bring the pinion 11 thereon into engagement with afixed driving-gear 14, here shown as an internal gear. Upon suchengagement taking place, the sleeve and the shaft upon whichcit ismounted continue their rotation during the rotary movement of theturret.

Before, however, the actuated starting-arm 9 has left the projectedlatch, a resetting socket 9 at the end of the former, will have operatedto thrust the latch outward, thus permitting the rengagement of thenotch 8 of the latch with the edge of the opening in the latch-frame.During the further rotation of the turret, the independent rotation ofthe shaft 5 and its connected parts continues until after the die haspassed the working point, whereupon a cam-arm 15 attached to therotating shaft will be brought into engagement with a cam 16 having acam face oppositely-inclined to the cam-face of the cam 13 and whichoperates to cause the shifting of the sleeve 10 in the opposite direction, and consequently the disengagement of the pinion 11 from thedriving gear 14, With this release of the pinion 1 1 the positiverotation of the shaft 5 about its own aXis ceases, and to insure correctpositioning of such shaft and consequently of the die-carrier attachedthereto, (which, it will be understood, is essential in order that theproper amount of rotative movement of the diecarrier may take place atthe next die selection,) there may be provided a suitable detent devicefor stopping the movement of the carrier in a definite position upon therelease of its pinion 11. This device, as herein shown, comprises aspring-pressed plunger 17 suitably mounted to cooperate with a flattenedportion of the shaft, and operating as a brake to arrest the rotation ofthe shaft in a position in which the plunger is in contact with suchflattened portion.

The present mechanism embraces means for automatically feeding a blankor other member through the instrumentality of a selected and rotatingdie-carrier during the revolution of the latter around the axis of theturret shaft, the feeding of such member being under the control ofparts coordinated with the selected die thereon. Entering upon adescription. in detail of the various features of this portion of themechanism, each die-carrier is provided with a number of facescoordinated with the dies on the carrier and each adapted during themovement of the die to which it is related to the working point foreffecting the movement through intervening mechanism of the element oractuator hereinbefore referred to. These feedfaces, designated by 18without preference, are herein shown as shoulders formed by the endwalls of recesses which. are conveniently and as shown herein made inthe radial face of each pinion 11; and to enable such feedfaces toregulate the variable movements of the blank, they are shown ofdiiferent radial depths, since, when so constructed, they are adapted toeffect the described movements of the blank.

As an engaging pinion 11 rolls around the surface of the driving-gear, afeed-face 18,

corresponding to that die which will ultimately roll over the blank atthe working point, is brought into engagement with a pin 19 extendingfrom an arm 20 pivoted to a rock-lever 20 fastened to a rock-shaft 21.The normal position of this rock-shaft is de termined by a spring 2].,which tends to turn the shaft and bring a stop-arm 22 thereon. intocontact with a stop-pin 23 projecting from a fixed portion of themachine. As the die-carrier continues its orbital movement with the pin19 in engagement with the feed-face, the pin is carried outward; andthrough the described connection the rockshaft is rocked in. itsbearings until, as the die-carrier continues its movement, the arm 20 isdeflected from its position, and the die-carrier leaves the pin 19. Inorder to insure the correct and normal positioning of the arm 20 withthe pin 19 disposed in the path of a selected and rotating die-carrier,I have shown a spring-arm 2% extending from the arm and located betweenstops 2525. As a result of the action of spring 21 and the spring-arm24, the rock-shaft 21 and the parts mounted thereon are caused to assumetheir proper relative position to cooperate with a feed-face on adie-carrier when the latter is next set in rotation.

The intermittent angular movement of the rock-shaft 21 is transmitted toa shaft 26 mounted in. hearings in the body of the internal gear 14, andin the latch-frame 7, the transmitting mechanism embodying a link 27pivoted at one end to an arm 28 extending from the shaft 21, and at theother end to a pawl-carrier 29, supporting a spring-pressed pawl 30engaging with a ratchet-wheel 31 secured to the shaft 26. The arm 28 isshown A as extended forming a hand-lever (see 32) to enable the shaft 26to be rocked manually, when desired. From this shaft 26 motion istransmitted to the feed element or actuator already referrred to.

As illustrated in the drawings attached to the present specification,the member adapted to be fed under the dies and on which the latteroperate to form a determinate succession of types as the dies roll inturn over its edge, is shown as a blank whose type-forming portion oredge is integral with the body of the blank. It will be understood,however, that the invention is applicable to the feed ing of othermemoers, such, for instance, as a typebar body or type-carrier.

in the mechanism set forth in my first hereinbefore mentionedapplication, the blank is fed under the dies in the plane of rotation ofthe die-carriers and this is the case in the present illustratedembodimeir of the invention. It will be understood in this case,however, as in the former, that this specified relation is chosen merelyfor illustrative purposes, and in no wise constitutes a limitation ofthe present invention. The blank, furthermore, in my companionapplication, is represented as a short length blank; that is, one Whoselength is approximately equal to the length of the line of types to bemade and while, of course, the present construction is suited to thefeeding of such a form of blank, I have illustrated the blank herein asbeing the form of a continuous ribbon or strip, designated in a generalway by C, and

conveniently fed from a reel VJ, upon which the blank is coiled around acenter U having a notch it with which the inner end of the blank isengaged.

The blank is adapted to be fed through a slot formed. betweenside-pieces or uprights 33, 34, serving to support and maintain theblank in a fixed position during the rolling movements of the dies. Inorder that that blank may lead freely through the slot between theuprights, I preferably so mount the reel W as to enable it to shift itsposition as the blank is withdrawn from the supply coil, and thediameter of the latter diminishes with the consumption of the blank.

As constructed in the present instance, the reel W is mounted upon aswinging arm X pivoted in any desired way, for instance, by a pin X, tothe base late B of the machine, the reel and the coi being preferablyconstantly urged into a position, as by a spring Y, in which the blank,immediately prior to its separation from the coil, impinges against astop-roller 1* mounted upon a fixed portion of the base plate, thusenabling the blank, after passing through a pair of guide-rollers s, s,to enter the slot between the uprights 33, 34, the alinement of theblank with such slot being assured by the position of the rollers s, 8.Obviously the separate typebar-lengths may be severed from theribbon-blank by any suitable means subsequent to the formation of thetypes on the edge of the blank.

I prefer to have the actuator or that element whose movement serves toshift the blank step by step through the supporting slot between theuprights 33, 34, engage .directly with the face of the blank, since sucha construction is convenient and necessitates but few parts. Theactuator designated in a general way by E, and constituting a feature ofthe present invention, is in the nature of a combined shoulder-formingand shoulder-engaging actuator, the operation of which serves tosimultaneously form shoulders in the face of the blank and engage withthe shoulders so formed. That is to say, during the movement of theactuator, it performs two functions, to wit: the notching of the face ofthe blank to form shoulders therein, and by engagement with suchshoulders to cause the feeding of the blank forward. This actuato mayconveniently be for-med as a single integral member, and, as shown inthe present case, it is a rotatable member having a helical Working faceor thread upon its periphery whose form is that of the so- 1 sponding tothat adjacent to the cusp of a called ratchet thread. By channeling orfiuting the periphery of the actuator to an extent sufficient tointersect adjacent portions of the thread or threads, teeth are formedthereon, which, when the actuator is :rotated, serve to notch the faceof the blank (see the notch c, Fig. 8) and form shoulders therein,

which shoulders, as the blank moves forward, are engaged by the oppositeend of the actuator, and when the latter is rotated cause the advance ofthe blank. The actuator will be provided with a suitable shaft 36,mounted in proper bearings, such as 36, 36. The shaft 36 may beconveniently driven from the shaft 26 by means of bevel gears, such, forinstance, as 37 and 38.

A machine organized and constructed, as illustrated and described,operates substantially in the following manner :Assuming a key K to havebeen actuated andthe attached latch L to be in its innermost position(the turret being in rotation), when the starting-arm 9, which islocated in the plane of that series of latches of which the proj ectedlatch forms a member, comes in contact with the latch, the rotation ofthe shaft- 5 will commence, the sleeve 10 surrounding such shaftrotating with it. Some time before the starting-arm leaves the latch,the cam-arm 12 will be brought into engagement with the cam surface ofthe cam 13, and the pinion 11 will be shifted into engagement with thedriving gear 1 1, as already described. The shaft 5 will now continueits rotation, but before the starting-arm disengages itself from thelatch, the latch will have been thrust inward, in the described manner,to cause the rengagement of the notch Z with the latch frame 7resulting, in consequence, in the holding of the latch in its outward ornormal position. Before the die, to which the projected latch isrelated, reaches the working point, the feed-face 18 on the radial faceof the rotating and revolving pinion 11 will be brought into engagementwith the pin 19, and the rock-shaft 21 will be rocked in its bearings,causing, it will be readily understood from the foregoing description,the angular movement of the shaft 26, and throughv the interveningmechanism the partial rotation of the actuator E. The teeth on thisactuator operate to notch the blank, and the latter will,simultaneously, be shifted lengthwise of the slot between the supportinguprights 33 34 into a position in which the proper portion of the edgeof the blank is brought under the die, the extent of this movement beingdetermined by the throw of the rock-lever 20, which in turn isdetermined, as already described, by the radial depth of the recess inthe face of the pinion. As the given die nears its working position, itwill approach the edge of the blank along a path correcycloid, and as itleaves the blank after rolling over the same, it will describe thesecond or complementary branch of the cycloidalcurve adjacent to suchcusp. At the same time, and subsequent to the disengagement of the diefrom the blank, the cam-arm 15 will, byreason of the continued movementof the parts, be brought into engagement with the cam 16, whereupon thesleeve 10, and hence the pinion 11 attached thereto, will be shifted inthe opposite direction and the latter disengaged fromthe driving gear14. The rotary movement of the shaft 5 about its axis is now free to bechecked, a result which follows from the performance by the plunger 17of its function as a precision brake, ultimately locating the shaft inthe same normal rotarial position. Such substantially is the operationof the various features embodied in the illustrated mechanism, theaction being repeated at each actuation of a key, while the extent towhich the blank is fed varies with the particular die chosen, in theevent that this is desired, and there is an existing variation in thedepth of the feed recesses, as described.

In using the term blank, I wish to include any and all elementsanalogous thereto as adverted to in the foregoing.
